Abstract
The present invention solves a problem that has been a barrier to development of high resolution ultrasonic imaging. It is based on an analysis that formulates the 5 problem of wave propagation in an inhomogeneous medium as a summation of an ideal wave and distortion waves. This analysis then leads to an apparatus that includes a forward propagation apparatus that enables measurement of the distortion waves and determination of corrections that are applied to originally received signals such that the ideal wave is left as the only basis for the final output signal. After signals are corrected, basic beamforming processes work as if the propagation medium was homogeneous such that ideal high resolution performance is achievable. The method is generally useful for improving any form of wave propagation system that is disturbed by inhomogeneities in the medium.
